Abstract

Polyethylene glycol (PEG) end-capped trifluorovinyl ether (TFVE) telechelomer was synthesized in one step via esterification of 4-(trifluorovinyloxy) benzoic acid. The new telechelomer was characterized by attenuated total reflectance Fourier transform infrared (ATR-FTIR), elemental analysis, and by F-19 and H-1 nuclear magnetic resonance (NMR) spectroscopy. The telechelomer and 4,4-bis(4-trifluorovinyloxy)biphenyl (BPVE) were thermally copolymerized via step-growth [2+2] cycloaddition at 160 degrees C. The polymerization afforded PEG enchained biphenyl perfluorocyclobutyl (BP-PFCB) copolymers that are solution processable and film forming. These copolymers were characterized by ATR-FTIR, F-19 NMR, and H-1 NMR. Gel permeation chromatography (GPC) gave number-average molecular weight (M-n) ranging 11,000 to 12,000. Compatibilization of PEG and a commercial polymer BP-PFCB was achieved utilizing the new PEG BP-PFCB copolymer, 3-co2-4. It was found that 5wt% of 3-co2-4 was ideal to reduce interfacial tension by scanning electron microscope (SEM). In addition, phase homogeneity was studied by differential scanning calorimetry (DSC).
